Mobile phone battery explosion, Guangzhou cited fears the U.S. blog

Beijing Feb. 5 news, the Guangzhou recently occurred in mobile phone battery explosion and led to one death. CNET tech blog Chris Matyszczyk Zhou Sanzhuan website text, mobile phone batteries on the U.S. market expressed concern about the security situation.

Matyszczyk pointed out that this is the place since 2002, the 9th explosion from the mobile phone battery.

This prompted him to consider giving up his old Nokia phone, the replacement of the newer products. Chinese police have not disclosed your phone or mobile phone battery manufacturers, but Nokia and Motorola have released a statement saying that the accident has nothing to do with them.Dell Latitude D620 Adapter Dell XPS M140 Adapter Dell PA-10 Adapter

CNET sites Matyszczyk is the famous "technology skepticism" were. He hoped that science and technology experts to come forward and explain why mobile phone battery explosion causing death, he also wished to know the U.S. market, the likelihood of similar incidents.

He said that if there is enough information to prove that he uses the phone battery is a security risk, he could go to AT & T stores, AT & T requested a refund. Although he did not think the U.S. market, the lethal phone similar incidents, but Matt Asay, and Don Reisinger and other leading U.S. technology blog article comments are still some worrying is often discussed.

Matyszczyk said, AT & T and other operators of mobile phone batteries should be made to clarify the security situation in order to appease the users emotions.

Cited public concern about mobile phone battery explosion expert advice to the cottage battery say

Recently, the phone also frequently hit the newspapers reported an explosion. Recently, the Guangzhou twice a day continuously for mobile phone battery explosion occurred, a chest blasted employees; a woman Huarong damaged, leaving a 2 cm scar. Matter in the media, the cause of great concern to the people in our city. People are talking about: what kind of battery is safe? How to use the mobile phone battery was reliable?

"Now what is at risk, did not expect such a small battery causing great harm can escape. Authorities really should pay attention to these problems, severe punishment of the manufacturers who produce defective products." Namhong Street, who lives in the alley Liu Hongyuan also encountered mobile phone battery explosion, but fortunately did not lead to misfortune. One day last September, he was charging the phone battery power, went to the bathroom on the toilet, but a few minutes he heard several more explosions, and when he went to the room only to find glass has been blown to the ground, and the phone equipment has been broken where the battery, the battery only has a core. Liu told reporters that the use of mobile phone original battery standby time is very short time is too long to just buy a piece of first use the battery, fortunately, was not there, or really do not know what could happen.Dell Inspiron 9300 Adapter Dell Inspiron 9400 AC Adapter Dell Inspiron e1505 Adapter Dell Inspiron e1705 AC Adapter 

Leyden Energy’s three-year warranty battery will cost a premium over a standard one-year battery, and while Leyden Energy hasn’t yet determined the exact price it will sell the battery for, Leyden Energy CEO and President Aakar Patel told me in an interview that a three-year battery will be less than double the cost of a one-year battery. Leyden Energy will also announce a deal Monday to sell its battery through the Canadian battery retailer Dr. Battery, and interested customers will be able to buy the battery online in a couple of weeks through the retailer.

Leyden Energy was founded in 2007 with a patent acquired from chemical giant Dupont, and a $4.5 million investment from investors at Walden International, Lightspeed Venture Partners and Sigma Partners. Leyden’s secret sauce is an innovation for the electrolyte part of the battery. A battery has a positive and a negative plate and then an electrolyte in between, which is the substance through which electrons transfer back and forth while the battery charges and discharges.

While standard lithium-ion batteries use a salt-based solvent within the electrolyte that starts degrading at a temperature of between 70 to 80 degrees Celsius, Leyden uses a salt-solvent in its electrolyte that doesn’t degrade up to temperatures of 300 degrees Celsius. Leyden Energy holds a patent for this innovation. As Patel explained it to me, when a battery charges and discharges, think of the electrons as rods that move across the electrolyte (between the anode and the cathode) and fill holes on the other side. After a certain point in time, standard electrolytes, particularly at high temperatures, let the rods start to break down and the holes start to fill up, but Leyden’s battery can maintain the integrity of those rods and holes at higher temperatures for a longer period of time.Dell Inspiron 1501 Adapter Dell Inspiron 6000 Adapter Dell Inspiron 6400 Adapter Dell Inspiron 9200 Adapter 

In the grand scheme of innovations, and with startups trying to change the game with designs for battery-powered cars with hundreds of miles of range, Leyden’s innovation is kind of like baby steps. But if Leyden can manage to get a deal with a major laptop manufacturer to embed the battery directly in a laptop, or market the battery with a popular laptop, then the company could do well. In 2008, Boston Power launched its three-year-lasting lithium-ion battery with laptop maker HP, and is backed by Oak Investment Partners, Venrock, GGV Capital and Gabriel Venture Partners.

Like Boston Power, Leyden Energy has been eying the electric vehicle battery market, too, and is working with Brammo to supply the battery for its electric motorcycle the Empulse, a more powerful version of Brammo’s original e-scooter the Enertia (which I test drove here). Leyden and a vehicle maker partner were also awarded a $2.96 million grant from the California Energy Commission to produce ten electric vehicle batteries per month. Leyden seems like it’s focusing more on batteries for the laptop and consumer electronics markets, instead of electric vehicles, as it seems like the market for electric vehicles is moving slower than some have expected.
